220i & 228i Flash Tuning

Just sharing some recent results of N20 Flash tuning applicable to the 220i and 228i, as well as F20 125i.

Generally we would expect the following baseline figures

220i: ~115kw at the wheels
228i: ~150kw at the wheels

Given the engines are near identical after tuning we expect both to be around mid to high 170s with no other modifications. Downpipe, exhaust and intake can see these crack 200rwkw

Compared to JB4s etc on a 228i they will typically dyno at low 170 rwkw (less torque aswell) and on the 220i you are looking at mid 130 rwkw

If anyone has a 220i I can't recommend a flash tune strongly enough as the gains are in excess of 60kw at the wheels, which frankly makes a 220i + tune a performance bargain

F20 125i Stock: 149rwkw, Tuned: 179rwkw, gain of 30kw & 20%


F30 320i Stock: 114rwkw, Tuned: 174rwkw, gain of 60kw & 52%

220i ECU Flash

Purchased a 220i (N20) recently primarily for its handling performance and the fact that it's not on the RTA banned list - which means my daughter can drive it. The stock 220i has a real flat spot at 1500 rpm when cruising in comfort mode.

The auto box seems to want to put the car in this flat spot all the time. Hence, I tended to use it in manual mode during most driving situations so that I could keep the revs up a bit. Driving it in sports mode pumps this up 500 rpm or so misses this flat spot -but overall the car as we all know can handle a lot more than it's factory tune.

Got Stuart from BMR to work his ECU Flash tune black magic on the car - it's now totally transformed the driving experience. Wife's got a Macan Petrol S. Yet to drag race her (we are both 50 and do not own any baseball caps) - but I think I can now keep up with her Porsche (at least to 100 km/h).

For those with warranty questions - I did this with a car that has done 3000km and has 2 yrs and 11 months warranty left. You only live once! Personally I've driven for 34 yrs - mainly high performance euros. Not once in that time have I ever had a drivetrain issue that required a warranty repair. Not once.
